Low-Power Tunable Micro-Plasma Device for Efficient and Scalable CO₂ Valorization.

ABSTRACT: Valorizing CO₂ into chemical building blocks via efficient electrified processes could significantly decrease carbon emissions. In this work, a device that allows generation of tunable micro-plasma modes (arc, pulsed, pulsed arc) on a chip for efficient, low-power and renewable chemical production is presented. This concept is first demonstrated by using nanosecond repetitively pulsed (NRP) micro-plasma for pure CO₂ splitting and show that the pulse micro-plasma maintains a peak energy efficiency of 29% across 0.2%-21% CO₂ conversion at plasma powers below 1 W-nearly an order of magnitude lower power than other systems with comparable performance. The kinetic studies feature pulsed arc mode as a novel way to improve CO₂ conversion, where CO produ
